A Franklin man will spend nearly two decades in federal prison for child pornography.

Gary Dismore, 42, pleaded guilty to advertising, distributing, receiving, and possessing child pornography.

Dinsmore was sentenced Friday to 15 years in federal prison.

Indiana State Police began investigating Dismore in November 2017.

Federal prosecutors said Dismore had been uploading, sharing, and storing explicit photos and videos since at least 2007.

"Individuals who choose to sexually exploit and prey on innocent children will be prosecuted to the full extent under federal law," said U.S. Attorney Josh Minkler. "The U.S. Attorney’s Office is committed to safeguarding children against child predators, like Dismore."

Dismore will spend 10 years on probation after his release from prison.
